Rail Network
https://geodata.bts.gov/maps/north-american-rail-network-lines

North American Rail Network (NARN) can be used within the public, the federal government, rail industry, state DOTs, and academia for routing, mapping and analysis. The North American Rail Network (NARN) Rail Lines dataset was created in 2016 and was updated on October 12, 2023 from the Federal Railroad Administration (FRA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The NARN Rail Lines dataset is a database that provides ownership, trackage rights, type, passenger, STRACNET, and geographic reference for North America's railway system at 1:24,000 or better within the United States. The data set covers all 50 States, the District of Columbia, Mexico, and Canada.

North American Rail Network (NARN) can be used within the public, the federal government, rail industry, state DOTs, and academia for routing, mapping and analysis. The North American Rail Network (NARN) Rail Lines: Class I Freight Railroads View dataset is from the Federal Railroad Administration (FRA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This dataset is a subset of the NARN Rail Lines dataset that show the ownership and trackage rights for all the Class I freight railroads: “Burlington Northern and Santa Fe (BNSF),” "Canadian National (CN) Railway," "Canadian Pacific (CP) Railway," "CSX Transportation," "Norfolk Southern (NS) Railway," "Kansas City Southern (KCS) Railway," and "Union Pacific (UP)". It is derived from the North American Rail Network (NARN) Lines dataset, and for more information please consult, https://doi.org/10.21949/1519415. The NARN Rail Lines dataset is a database that provides ownership, trackage rights, type, passenger, STRACNET, and geographic reference for North America's railway system at 1:24,000 or better within the United States. The data set covers all 50 States, the District of Columbia, Mexico, and Canada.


Marine Highways
https://geodata.bts.gov/maps/marine-highways

This data provides users with information about the marine highway locations for national and regional analysis applications. The Marine Highways dataset was created on June 15, 2016 and was updated on October 31, 2023 by the U.S. Maritime Administration (MARAD) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). MARAD's Marine Highway Program is a Maritime Administration led program to expand the use of our Nation's navigable waterways to relieve landside congestion, reduce air emissions, and generate other public benefits by increasing the efficiency of the surface transportation system. This dataset contains the locations of all 28 maritime routes that have been designated as Marine Highways by the Secretary of U.S. DOT. Routes included in this dataset are diagrammatic and may not depict all waterways and port connectors that are considered to be part of the U.S. Marine Highway System.
